- Can you point me towards any evidence on this? A very cursory
- literature search turns up only peripheral reference: Quan et al, "The
- effects of microwave radiation on anti-infective factors in human
- milk" in Pediatrics, Apr 1992.
-
- The article is not about freezing per se, but rather reports
- experimental evidence that microwaving milk reduces its antibacterial
- effectiveness. (i.e. a fivefold increase in e. coli growth in samples
- that had been heated in a microwave, even to as little as 20-25
- degrees C.)
-
- The research is relevant to this question because it used frozen
- milk in both the subject and control conditions, and found significant
- antigen activity in the thawed (but not heated) milk.
